Have just upgraded to Outlook 2007. I created several signatures but have
left the default signature set to "none" so that I can insert the one that
is appropriate for the individual message I am composing.

So I opened a new message, filled in the recipient and the subject, typed
the message, and then clicked on Insert \ Signature. I double clicked the
one I wanted to use on this message and nothing happened. I have tried to
insert each of the three different signatures, and none of them will insert
even though all three of them show up as choices.

What am I missing??
